Today’s article is a bit more technical in nature but is designed to put some more complex ideas and concepts in layman’s terms.
Q1. What size HVAC (Heating, Ventilation, Air Conditioning) system should I have?
Bigger isn’t always better. Often times we find systems that are oversized or people request a bigger unit because they think it will work better. But oversizing the unit can be costly because you’re trying to heat or cool space that isn’t there. On the flip-side an undersized unit will run constantly as it is trying to meet your needs and will still end up costing you extra money. The size is determined based on many factors such as square footage of your home, type of building materials and setup of the home, insulation values and number of windows and doors. Even the direction those windows face and how many people live in the home effect what size system is needed! The only way to ensure a proper MEASUREMENT of your needed system requirements is to use a qualified and experienced home comfort consultant from ServiceMark. We are experienced in doing load calculations to determine the proper heat loss/heat gain in your home. Then we’ll provide the proper information on not only the needed system size but options on efficiencies and all the timely information on government tax credits, and industry and utility rebates.
Q2. How is the efficiency of a heater or air conditioner measured?
SEER rating – Seasonal Energy Efficiency Rating – the higher the SEER number the less it will cost to operate.
HSPF rating – Heating Seasonal Performance Factor – like the SEER rating this accurate ratio also tells you what systems save operational money over others.
AFUE rating – Annual Fuel Utilization Efficiency – this is a measurement of the percentage of usable heat produced by a furnace for every dollar spent. Again, the higher the percentage the less cost to operate. Systems falling below 78% are VERY inefficient. Units that range upwards to 80% are considered mid-range efficiency systems. Equipment with ratings at 90% or higher are considered high efficiency models and save the most!
